he means while youre getting an oil change they tend to try and sell you other services they say are needed immediately years back when i actually took my car to them they would always give me shit about my tranny fluids and brake fluids etc i always told them to piss off and finish my oil change the last straw was them being rude to my wife telling her its your car to ruin we just wanted to help went to change the oil the next time and they use cheap nameless mexican filters fuck that never again will they touch my cars
